Description

Scotts® WeedEx™ Prevent with Halts® prevents crabgrass and other problem weeds for a beautiful lawn all season long. In early spring, apply when the lawn is dry to prevent the germination of crabgrass, foxtail, spurge, barnyardgrass, fall panicum, and oxalis. Apply in the fall (August-October) to prevent moss (except in California), or to prevent the germination of Poa annua, henbit, corn speedwell, and chickweed. We recommend using a Scotts® spreader to apply this product. For Scotts® broadcast/rotary spreaders, use a setting of 2 ¼. For Scotts® drop spreaders, use a setting of 4 ½. For Scotts® Wizz®, use a setting of 3 ¼. For best results, the lawn should receive ¼ to ½ inch of water from rainfall or watering within 2-3 days after application. Rain, snow, or freezing weather after application will not affect performance. This product controls crabgrass in its early stages of growth. It does not control mature crabgrass and other existing weeds. Do not apply to Dichondra and Bentgrass. One 10.06 lb. bag of Scotts® WeedEx™ Prevent with Halts® covers 5,000 sq. ft.

How to Use

  • Check bag for spreader setting
  • When using a Scotts® broadcast or Wizz® spreader, make a perimeter pass of your lawn with EdgeGuard® on to protect non-lawn areas. Then, make parallel internal passes 5 ft. apart to ensure even coverage.
  • When using a Scotts drop spreader, start 5 feet from the edge of your lawn and walk the outline of your lawn. Then, make internal passes across your lawn, overlapping the wheel marks to ensure uniform coverage.

Where Not to Use

  • Do NOT apply to dichondra or bentgrass lawns

Where to Use

  • Can be used on all lawn and grass types EXCEPT dichondra and bentgrass

When to Apply

  • Apply once in spring and once in the fall
  • In southern California, apply before March 1st
  • In northern California, apply before mid-March

How Often to Apply

  • Apply a maximum of twice a year with a minimum of 2 months between applications

Watering Tips

  • It is not necessary to water in immediately. For best results, lightly water the lawn to rinse particles from grass blades (up to ¼ to ½ inch) within 2-3 days after application.

Using with Other Products

  • Follow with Scotts® Turf Builder® Weed & Feed or with Scotts® Weed Control for Lawns

Rated 5 out of 5 by from Quality product I received my Scotts just in time for the spring use. I have a small yard so I am able to make another application for the fall. Since my application I have noticed a significant difference in the crab grass growth in the yard for the better. I am waiting for the fall application to see how my yard looks . I take care of my yard myself and don't rely on a service so I want to make sure I know what is going down on my grass using a quality product. I will be using the Scotts lawn product again.

Rated 5 out of 5 by from This Product Puts the Pros to shame Scotts lawn product are top of the line. I recently used Scotts with Weedex for the first time and I am NOT disappointed. Days after the treatment I could tell the grass was greener and thicker. I was a little late applying so I did have to treat for weeds prior to use but I won't have to worry about that again til the Fall thanks to Weedex. Several of my neighbors use lawn services but my lawn looks as good as any and better than most. There is one lawn across the street that always looks better (even in the dead of winter) but I have seen his lawn being treated and it looks like they might be spraying paint or dye on it LOL. I prefer a good healthy lawn and am very pleased with the results I have repeatedly gotten from Scotts products. There are cheaper products but none that I have found are as good. I highly recommend this product to anyone looking to improve the health and appearance of their lawn. Thank you Scotts!

Rated 5 out of 5 by from Nice product I like the size of the bag. Anything over 10 lbs might be too heavy for some people to lift safely. The directions were clear & I would recommend this product. I would use this product again if I needed it.

Rated 5 out of 5 by from Good Product Scott’s Weedex Prevent with Halts is a good product. Applied as directed it does keep crabgrass from sprouting in your yard for months. I do find a mid summer re-application does help with late sprouting crabgrass in late summer and early fall. The product is easy to apply with a drop or broadcast spreader. I would recommend this produc.

Rated 5 out of 5 by from Great This was a game changer for me this Spring. I finally decided to overseed the back yard and a patch in the front and didn't want to put this product on too soon. IT is a great product and is easily dispersed right where you want it to go to avoid waste and areas not really intended for it.

Rated 5 out of 5 by from Took care of crabgrass I applied it his early spring (in Michigan) and there is evidence that it has prevented pre emergent crabgrass. Easy to apply with great results. I have not noticed if it had any effect on my clover yet but we will see within the next few weeks. I would recommend.

Rated 5 out of 5 by from Great for getting rid of stubborn crab grass! I love how great this made my lawn look! It was easy to apply and I noticed a lot less crab grass on my lawn. My lawn looks plush and green with none of those nasty weeds! I put this in my spreader and just use that to spread it on my lawn and it went on great and it was easy to do!

Rated 5 out of 5 by from Clears clover and grows thick lawn We live in an agricultural area and our house wasbuilt in1875. The lawn wasn't taken care of mainly because of chickens and bunny's living around us. The side yard is pretty thick with patches of clover. The Scotts WeedEx Prevent with Halt is made to clear that cliver so healthy grass can be grown. My husband used a spreader where the clover was abundant and applied it before the week of rain came. Huge difference! Clover was gone, grass was greener, thicker and more lush than ever before. Excellent product, Scott's always makes the best lawn care for homeowners!! Thank you~
